WHAT exactly are Royal visits for? The answer - at some level - is always political. Unless, like Daily Mail columnist Sarah Vine (aka Mrs Michael Gove) you think that the Cambridges turning up in the devolved nations this week was all about royal “moral-boosting” in a time of plague. For the record: the government of the day always approves any major royal activity. Or did you think (like our Sarah) that the William and Kate just happened to turn up in Scotland, Wales and the North of England when Boris was flag waving over the new vaccine and rushing to Brussels to put those pesky Europeans in their place.
